Yes!
That did it
I copied the ivpbot_i486.so to ivpbot_i386.so (couldn't remember the copy command for a symbolic link sorry).
And after that i got the same error as Telston.
I was missing the same library, Probably something RH9 doesn't install with the options i choose (server install).
After looking for the right RPM i found this one
compat-libstdc++-7.3-2.96.118.i386.rpm (was included on my cd but here's the link for people who don't have it). After installing that the library was there.
I tried to start the server after that and it worked
I even got it running with metamod/adminmod now.
Thanks a lot, now we can finally practice on some bots.
Thanks again for the solution and the excellent program.
